Antonio Fernandez, Weatherford International

I find it amazing that a device originally designed and patented in 1936 is still the mainstay of hardness testing for most shops. Not many products that are in existence in this day and age like that. True testimony of what a well thought out product it is.

John Rodney, Southwest Heat Treat

I really appreciated the tremendous customer service.

Bill Arenburg, CarlisleIT
